Sustainable Self‐Healing of Perovskite Solar Cells Using Dendrimers as Volatile Reservoirs

open access: yesAdvanced Materials, Volume 38, Issue 5, 22 January 2026.
Sustainable self‐healing perovskite solar cells (PSCs) are developed through the incorporation of dendrimers with unique molecular structures and appropriately placed functional groups. Notably, even after subjecting ten harsh degradation and recovery cycles, these PSCs maintain 90% of their initial power conversion efficiency (>26%).

Impact of Grain Size on Low‐Temperature Carrier Phase Coherence Length in Polycrystalline Halide Perovskite Films

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
Magnetoresistance measurements on a series of polycrystalline cesium tin iodide (CsSnI3) thin film devices having varying grain sizes reveal no power law dependence with clear signatures of weak anti‐localization (spin‐orbit coupling). Surprisingly, the extracted phase coherence lengths are found to be independent of grain sizes.

Revealing Two Operation Modes of Perovskite Light‐Emitting Diodes Through Overshoot Pulses

open access: yesAdvanced Photonics Research, Volume 7, Issue 1, January 2026.
Short, high‐intensity overshoot pulses (OSPs) may be generated by perovskite light‐emitting diodes (PeLEDs) depending on electrical pump pulse parameters, offset and afterpulse voltages. OSPs reveal two PeLED operation modes: the recombination mode, favorable for the conventional EL but preventing OSPs, and the accumulation mode, enabling the formation

High‐Efficiency Semitransparent Solar Cells Based on Magnetron Sputtered Sb2S3 Thin Films

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
Compact Sb2S3 films are deposited via RF magnetron sputtering using an Sb2S3 target. Post‐deposition annealing conditions are optimized to achieve a power conversion efficiency of 4.6%. Semitransparent solar cells are then fabricated with transparent top electrodes, resulting in an average visible transmittance of over 20%.

Supramolecular Macrocyclic Iodine Adsorbents Enable Photothermally Stable Perovskite Solar Cells

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
Two novel diazapentacene‐based macrocycles are synthesized with expanded cavities that enable dual‐mode iodine adsorption through both physical and chemical interactions. When applied as iodine adsorbents in solar cells, PSCs incorporating M4 achieve 26.13% efficiency with 95.85% retention after 1000 h at 85 °C.
